CHEVY POOR RUNNING

1997 Chevrolet Cheyenne

Engine Performance problem
1997 Chevy Cheyenne 6 cyl Four Wheel Drive Automatic 150k miles

I have a problem with the 97 chevy cheyenne. IT has a " hickup" and then bogs down and will hardly drive. Also has hesitation from a stop. Have replaced fuel filter, fuel pump, fuel spider, wires, plugs, evap cannister been serviced, cat converter, o2 sensors, coolant sensor, list goes on. Acts like a fuel problem. Please any help would be great.

Do you have a check engine light and when was the last tune-up?

Check the fuel pressure if its within specs if okay-test the airflow sensor, throttle position sensor, manifold absolute pressure sensor, this is just a few check and test and comeback with some results
